Given numbers are 570,203,655,989
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 570,203,655,989 is 14991271890.
Find LCM of 570,203,655,989 with Prime Factorization
| 5 | 570, 203, 655, 989 |
| 114, 203, 131, 989 |
Multiply the prime numbers at the bottom and the left side.
5 x 114 x 203 x 131 x 989 = 14991271890
Therefore, the lowest common multiple of 570,203,655,989 is 14991271890.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
570 x 203 x 655 x 989 = 74956359450
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570
203 : 1, 7, 29, 203
655 : 1, 5, 131, 655
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 570,203,655,989, is 1.
Now, the common factors can be found like this.
570:2x 3x 5x 19
203:7x 29
655:5x 131
989:23x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5 = 5
Therefore, the value for common factors is 5.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 74956359450/(1x5)
LCM = 74956359450/5
LCM = 14991271890
Thus, we can understand that the LCM of 570,203,655,989 is 14991271890.
